Iron Ore Mining Process Flow Chart
Magnetic iron ore mining process flow chart consists of vibrating feeder, trough feeder, jaw crusher, vibrating screen, ball mill, classifier, magnetic separator, concentrator and dryer and other major equipment components, with the feeder, elevator, conveyor can form a complete production line dressing (optional iron production line). The magnetic iron ore production line with high efficiency, low energy, high capacity, economical advantages.
New environmentally friendly magnetic separation process, a magnetic magnetite beneficiation process combined wet and dry method, magnetic separation process is mainly carried out three magnetic ore processed, and then the wet material magnetic separation, magnetic separation of the optional magnetic field strength of 400 ~ 1200GS, magnetic roller speed of 60 to 320 r / min, wet material obtained by dehydration of finished iron ore powder, usually iron ore content of 35% by this method after magnetic separation of iron ore powder iron content of up to 68 to 70%, the combined process method, ore utilization up to 90% less water in the process, save water, reduce costs, reduce pollution, in addition to magnetic dust from the crusher manufacturer dust collecting device will not cause air pollution, this method is a high production efficiency, product quality, pollution creative process method.
Iron ore crushing use sec, sec grinding and three sections of magnetic separation process, the particle size-0.074mm accounted for about 85% iron concentrate grade of 66%.
Stope ore shipped from the car to the ore dump yard, giving the ore loaders ore positions, positions under the 980mm1240mm trough feeder fed into the primary crusher, conveyor products fell No.l enter 1500mm × 3000mm shaker, sieve products into the crushing machine. Finely produced a drop ANo.3 conveyor, head of the suction dry sorter, transported to the grinding position; under sieve products by N0.2 draper head of the suction L dry sorter, transport to the grinding position.
Magnetic paragraphs are gravity tailings have entered the plant within the tailings pond pump, Yang sent to plant more than 200 m southwest of the tailings storage library, clarified water and tailings seepage water from the pump and then play back the production of J. Room recycling, backwater utilization up to 80%. Provided on the front cone crusher conveyor metal detectors, manual removal of iron, ore dressing equipment are strict national conventional equipment, but did not set up automatic control n p crushing equipment using next joint locks and machine operation, part of the pulp has detected instruments.
